====IPv4 and IPv6 addressing====
====IPv4 and IPv6 addressing====
Everything in this manual to date refers to IPv4 (IP version 4) addressing. The world is running out --well, has run out -- of IPv4 addresses. Various strategies have been adopted by ISPs to obscure and work-round this issue and much of the world is still running on IPv4.
Everything in this manual to date refers to IPv4 (IP version 4) addressing. The world is running out -- well, technically-speaking ''has'' run out -- of IPv4 addresses. Various strategies have been adopted by ISPs to obscure and work-round this issue and much of the world is still running on IPv4.
Nonetheless IPv6 addresses will have to be used at some future point, although few ISPs offer direct IP6 connectivity even in 2021. For now, all in this manual concerns IPv4 -- the underlying system is however fully IPv6 capable. Considerable extra work is called for, so as to integrate that support into the system, and this is not a priority for now; eventually of course it will be. If you wish to contribute to this work, please consider volunteering or offereing code.
